Oh, and whatever you enjoy playing. Since you're asking this question in the first place, any remotely difficult content is already ruled out, so it doesn't matter.

I'd say 90% of the time the tank is a warrior or a DK in heroics, in my experience.

I tank on my warrior myself, and my friend is a holy paladin. He said the few times he's had a druid tank, they've been "more difficult to heal." Whether that was because of the druid's playstyle or lack of ability would have to be studied further. Are you guys seeing a more diverse array of tanks or am I going crazy?

Druid tanks have it the worst because they don't deal with bleeds as well as the other tanks. A lot of raid level bosses tend to pack bleeds these days. A pack of mobs with bleeds can down a bear almost in a one shot if the healer is not ready for it.

Doesn't sound like they'll be fixing BrMs anytime soon either
"Monks are likely the class that needs the most work right now. Mistweavers have been difficult to balance, work on that is still ongoing. Healing and DPS Monks are also underrepresented in PvP."

To late! =P I shelved my DK for Monk and never have seen a reason to go back. At least on all normal mode fights I've been easier to heal than any other tank I've grouped with and my DPS puts most of them to shame.

The four elements, like man alone, are weak. But together they form the strong fifth element: Boron.

Monk tank seems to have some new mechanics for damage reduction. I healed awful geared monks through heroics with not much problem as well as decently geared monks with insane stress and difficulty to keep them up. once the player know what to do monk is pretty good tank (which can heal a ton if there is nothing to tank).

So from healer perspective its same every patch: skilled tank >>>>>> all other tanks (the class has minimal efect in general tanking)

If you grou struggle on enrages - DK or Druid,
If you lack raid CDs or healing - Monk or Pala
for fast mobile tanking - Warrior is king

Is probably a lack of skill. As a guardian tank, I find I need few heals since I know how to respond in most fights. New tanks will always struggle, but if the Druid truly knows what he/she is doing, the healing to a druid should be minimal.

Tanks are much more balanced this expac than at any other time. However, player skill is also probably playing the largest role it ever has in tanking. A lot of players still don't understand active mitigation (and TBH, Blizzard hasn't done them any favors here).

I'm sure by the end of the xpac we'll see dedicated tanking addons that are much better, and probably a lot of base UI tools that help out tanks as well. This should bring up the bottom of the curve quite a bit. Until then, the variability in tanking skill is going to heavily dominate over any minor differences in tank class balance.
